Bashar Masri, a Palestinian American billionaire, resigned from the Harvard Kennedy School’s Dean’s Council earlier this week, days after he was accused in a lawsuit of covertly building infrastructure for Hamas’ Oct. 7, 2023 terrorist attack. The complaint was filed on Monday in a Washington, D.C. federal court on behalf of more than 200 families of victims of the Oct. 7 attacks. It alleges that Masri’s companies — under the auspices of various real estate initiatives — were used by Hamas to conceal attacks, store and launch rockets against Israel, and produce electricity for its offensives.

An HKS spokesperson confirmed Masri’s resignation in a statement, writing that “the lawsuit raises serious allegations that should be vetted and addressed through the legal process.”

Masri had served on the Dean’s Council — a group of roughly 70 high-profile donors and business executives that directly advised HKS Dean Jeremy M. Weinstein — since 2014. Since 2018, Masri has also funded the Rawabi Fellowship, which pays for Palestinian students to attend HKS.

Masri did not respond to a request for comment Thursday afternoon after his resignation was first reported by the New York Post. He also denied the lawsuit’s claims in a statement to the New York Times.
